This powerpoint presentation begins by presenting a brief overview of Biological TreatmentProcess Fundamentals. Direct biological perchloratedestruction demonstration testingin Rialto, California, is presented and technical objectives included: evaluating efficacy of using fixed-bed (FXB) bioreactors andpost-treatment to convert perchlorate-contaminatedwater into potable water;demonstrate sustained removal capabilities;identify process limitations and potential failure scenarios; and,develop accurate full-scale facility lay-outs and costestimates. Pilot testing phases included:Phase I: Biological Acclimation;Phase II: Optimization;Phase III: Sustained Removal; and,Phase IV: Robustness Testing. EDR/BIOBROx perchloratedestruction pilot testing at theMagna Water District is presented, and had the following objectives: demonstrate efficacy BIOBROx approach;develop design criteria for blend ratio andEBCT;demonstrate sustained perchlorate removal;evaluate robustness of the process duringsystem upsets (system shut-downs, WWfeed failures, diurnal variations in WW); and,identify optimal biogrowth support medium. The experimental design included:Phase 1: Biological Acclimation;Phase 2: Percent Blend and EBCT Optimization;Phase 3: Sustained Removal; and,Phase 4: Robustness Characterization. Includes figures.
